I sat exhausted on my chair half asleep, dozing off every few seconds. My coworkers were no difference. I worked in NASA for the past three years. At first, working was fun, but after my boss believed of existing a new planet my world was upside down. I didn't eat lunch and would spent 24/7 looking at this screen searching for "any new planet". That seemed nonsense for me. I rested my head slowly on the chair looking at the screen with half closed eyes.

I grabbed my half drank soda and took a sip, but what I saw next on the screen made me spit the soda immediately. NO WAY!?!? Was that a …

… new planet?

Her soda had long gone flat from sitting on her desk for hours. Natalie didn't notice. She hadn't noticed the janitor emptying the bin beside her, or the gradual emptying of the floor around her, or the way Baltimore's skyline had stitched itself in lights beyond the Space Telescope Science Institute windows. She noticed only the data.

It was an anomaly, at first. A smudge in the photometric readout from Hubble's Wide Field Camera 3, easily dismissed as instrument noise, as a cosmic ray strike, as the universe clearing its throat. She had dismissed it once. Twice. On the third pass, something animal in her refused to let go.

You don't get three coincidences, her old professor used to say. You get one pattern.

Natalie pulled up the raw imaging data and began to layer the exposures: twelve hours of deep field observation stacked like transparencies, the noise cancelling out, the signal clarifying. Her fingers moved without conscious instruction. She had done this ten thousand times. She would know noise when she saw it.

This was not noise.

It sat at the edge of a red dwarf system catalogued as GJ 1151. A quiet, unremarkable, a star that had never warranted particular attention. But orbiting it, at a distance that placed it precisely within the liquid-water zone, was something that should not have been there. A rocky body with what appeared, in the spectroscopic overlay, to be an atmosphere.

Her heart performed a small, private revolution.

She ran the detection algorithm again. And again. She cross-referenced with the archival Kepler data, pulled the TESS lightcurve for the system, checked for any prior flag in the exoplanet database. Nothing. This world had been sitting in the dark for four billion years without a single human being knowing it existed.

Until now. Until her.

Natalie sat back in her chair. The room was almost entirely dark, lit only by the blue glow of her monitors. Outside, the city hummed its indifferent hum. Somewhere above it all, the Hubble telescope continued its silent orbit, gathering light that had travelled unimaginable distances just to fall, tonight, onto her instruments.

She thought about the planet -- her planet, for this one private moment before the emails and the peer review and the press releases dissolved the discovery into public property. She imagined its surface. Whether its oceans, if it had them, ran cobalt or green. Whether anything looked up from it and wondered, as she had wondered all her life, whether it was alone.

She picked up her flat soda and drank without tasting it.

Then she opened a new document, typed the system coordinates at the top, and began to write the paper that would change everything.

The title, for now, was simple.

Candidate Habitable World: GJ 1151d.

She paused. Then, in the margin, in letters too small for any collaborator to notice, she wrote a second title:

Hello.
